Record

2. Steps of the Day
Let’s Start
Definition of
Record
Application of
Record
Array of
Record

3. Definition of Record
All About Record

4. BackgroundofRecord
I need a program that similar with array
program but can be composed with
different data types.

5. WhatisRecord
Data structure that contains of several fields
(more than one) which has different data types.

6. Lecturer 1 Lecturer 2
NIP Name Address NIP Name Address
IlustrationofRecord Records were named Lecturer 1 and Lecture 2,
consists of 3 fields each of its.
Field
Name of Record

7. Lecturer 1 Lecturer 2
NIP Name Address NIP Name Address
IlustrationofRecord
Field
Name of Record
If you want to access NIP from Lecturer 1, yu
can do with Lecturer1.NIP

8. Application of Record
Definition and Structures of Record

9. StepsinRecord
• Declare record
• Initialize record
• Accessing record (input, operate,
and output)

10. Record Declaration (Algorithm)
Kamus:
type
TipeRecord = record
< field_1 : TipeData_1,
field_2 : TipeData_2,
..
field_n :TipeData_n >
endrecord
NamaRecord : TipeRecord

11. Example of Record Declaration (Algorithm)
Kamus:
type
RecordDosen = record
< NIP : integer,
Nama : string,
Gaji : real >
endrecord
Dosen : RecordDosen

12. Record Declaration (PASCAL)
type
TipeRecord = record
field_1 : TipeData_1;
field_2 : TipeData_2;
..
field_n :TipeData_n;
end;
var
NamaRecord : TipeRecord;

13. Example of Record Declaration (PASCAL)
type
RecordDosen = record
NIP : longint;
Nama : string;
Gaji : double;
end;
var
Dosen: RecordDosen;

14. Record Initialization (Algorithm)
Format:
NamaRecord.NamaField  DefaultValue
Example:
Dosen.NIP  0
Dosen.Nama  ‘’
Dosen.Gaji  0

15. Record Initialization (Pascal)
Format:
NamaRecord.NamaField := DefaultValue;
Example:
Dosen.NIP := 0;
Dosen.Nama := ‘’;
Dosen.Gaji := 0;

16. Input Value to Record (Algorithm)
Format:
input(NamaRecord.NamaField)
Example:
input(Dosen.NIP)
input(Dosen.Nama)
input(Dosen.Gaji)

17. Input Value to Record (Pascal)
Format:
readln(NamaRecord.NamaField);
Example:
readln(Dosen.NIP);
readln(Dosen.Nama);
readln(Dosen.Gaji);

18. Output Value from Record (Algorithm)
Format:
output(NamaRecord.NamaField)
Example:
output(Dosen.NIP)
output(Dosen.Nama)
output(Dosen.Gaji)

19. Output Value from Record (Pascal)
Format:
writeln(NamaRecord.NamaField);
Example:
writeln(Dosen.NIP);
writeln(Dosen.Nama);
writeln(Dosen.Gaji);

29. Array of Record
Definition and Structures of Array of Record

30. BackgroundofArrayofRecord
I have lecturer’s record but i need
lots of variables to declare
lecturers in program.

31. WhatisArrayofRecord
Record that declare using array’s form.
It can be made using all ways of array’s
declaration (three ways).

32. [1] [2]
NIP Name Address NIP Name Address
IlustrationofArrayofRecord Had been declared an array that had Lecturer
type consists of 3 fields each of element.
To access this i call Lecturer [1].NIP
Lecturer

33. Array of Record Declaration (Algorithm)
Kamus:
const
maks = value
type
TipeRecord = record
< field_1 : TipeData_1,
field_2 : TipeData_2,
..
field_n : TipeData_n >
endrecord
NamaArrayofRecord = array [1..maks] of TipeRecord
NamaRecord : NamaArrayofRecord

34. Example of Array of Record Declaration (Algorithm)
Kamus:
const
maks = 20
type
DosenIF = record
< NIP : integer,
Nama : string,
Gaji : real >
endrecord
ArrayDosenIF = array [1..maks] of DosenIF
Dosen: ArrayDosenIF

35. Array of Record Declaration (Pascal)
const
maks = value;
type
TipeRecord = record
field_1 : TipeData_1;
field_2 : TipeData_2;
..
field_n : TipeData_n;
end;
NamaArrayofRecord = array [1..maks] of TipeRecord;
var
NamaRecord : NamaArrayofRecord;

36. Example of Array of Record Declaration (Pascal)
const
maks = 20;
type
DosenIF = record
NIP : longint;
Nama : string;
Gaji : double;
end;
ArrayDosenIF = array [1..maks] of DosenIF;
var
Dosen: ArrayDosenIF;

37. Record Initialization (Algorithm)
Format:
NamaRecord[indeks].NamaField  DefaultValue
Example:
Dosen[1].NIP  0
Dosen[1].Nama  ‘’
Dosen[1].Gaji  0

38. Record Initialization (Pascal)
Format:
NamaRecord[indeks].NamaField := DefaultValue;
Example:
Dosen[1].NIP := 0;
Dosen[1].Nama := ‘’;
Dosen[1].Gaji := 0;

39. Input Value to Array of Record (Algorithm)
Format:
input(NamaRecord[indeks].NamaField)
Example:
input(Dosen[1].NIP)
input(Dosen[1].Nama)
input(Dosen[1].Gaji)

40. Input Value to Array of Record (Pascal)
Format:
readln(NamaRecord[indeks].NamaField);
Example:
readln(Dosen[1].NIP);
readln(Dosen[1].Nama);
readln(Dosen[1].Gaji);

41. Output Value from Array from Record (Algorithm)
Format:
output(NamaRecord[indeks].NamaField)
Example:
output(Dosen[1].NIP)
output(Dosen[1].Nama)
output(Dosen[1].Gaji)

42. Output Value from Array from Record (Pascal)
Format:
writeln(NamaRecord[indeks].NamaField);
Example:
writeln(Dosen[1].NIP);
writeln(Dosen[1].Nama);
writeln(Dosen[1].Gaji);
